I know this is easy to do and several years ago I remember doing it, but I haven't had time to get to some of my games in a few years. Now I'm running Parallels 6 on OS X. I have a few older games, like Myst. They were originally rendered for a smaller screen size. When I run the game, I want to tell Parallels to open it full-screen. I know this will not look great, but it's in my living room, where I'm sitting a ways back from the monitor, so there's a good chance it'll be okay. I remember, before, when I tried games like this, they originally opened in a smaller area (that matched the original resolution) with a huge black frame around it. I think there was a simple keypress that enlarged it to full screen. I searched for my older posts, but didn't find any with this question. How do I do this so my game fills the screen (at least in proportion to the window shape - I know it'll be letterboxed)?
